Since I started doing JDRF rides back in '05 I started logging my miles to this site www.bikejournal.com . It has been extremely helpful in keeping me motivated. Logging my miles after each ride and keeping a journal of the rides has helped me a lot in my training. I also include indoor training miles since those are the most brutal. I set up a club on the site called JDRF West Michigan if you want to join and you will be able to see how many miles everyone else is doing.
